I bought a nice doe kid who was horned and while she's not much trouble, I still have concerns about any possible "down-the-road" issues. Now I am looking at two new does to buy, both with horns. So I am interested in using my elastrator to band their horns. I printed some info about it but would love to hear from the "horse's mouth". What advice can all y'all give me? The doe kid I already have is almost 10 months old. The other two I am considering are almost two years old. I've heard age DOES make a difference.
